Western Digital is one of the biggest hard drive manufacturers in the world. Based in the USA and started in the 1970′s, Western Digital produced their first hard drives in mid 1980′s. Western Digital produce a wide range of hard drive products including desktop hard drives, laptop hard drives, solid state drives (SSD), external hard drives and other network and media storage devices.
Their consumer desktop range is named Caviar and comes in Blue, Green and Black series. Blue is for ‘every-day computing’, Green are the cooler, quiter and eco-friendly series, and Black are built for maximum performance and attract a longer warranty period. It is common to find these Caviar drives in capacities of anything from 20GB all the way up to 3TB (3,000GB).
Their laptop range of hard drives is named ‘Scorpio’ and come in the Blue and Black series similarly to the desktop range, with the Black hard drives having better performance and a longer warranty period. The Scorpio range currently have a maximum capacity of 1TB (1,000GB).
Western Digital drives are usually slightly more expensive than other brands. Certain models have been known to suffer from inherent PCB problems. Data recovery and repair involving Western Digital hard drives can be challenging considering the construction methods employed. In many cases the head stack is held in place, and aligned, with a screw in the top cover. Once this screw is loosened or removed for data recovery purposes the data recovery technician needs to work around this problem of re-alignment.
Hard drive data recovery relating to Western Digital hard drives includes:
- Logical data recovery involving repair of the file system stored on the hard drive, damaged by virus attacks, user error or hardware failure.
- Electrical data recovery involving repair or replacement of the main electrical components (PCB), damaged by static, bad power or surges, or user damage.
- Physical data recovery involving repair or replacement of the mechanical components within the hard drive internals. This includes replacement of the head stack assembly (HSA), motor spindle, or any other parts requiring repair or replacement. Damage to these components is often by wear and tear, manufacturing defects or user damage such as a drop or fall.
